Paul is correct: cover the light with sheets of minus green. I'd start with 1/4. If still getting green, add another layer to make 1/2 minus green (magenta.) Rosco and Lee both make minus green in various densities. Shop around. Adorama is probably a better source since B&H makes you buy 6 sheets at a time, I believe.
Obviously these units are DAYLIGHT balanced. If you combine them with tungsten lights, you will either need to add 1/2 to 3/4 CTO to the fluorescents as well, or else add 1/2 CTB to the tungsten units.
